pH- and ionic strength-dependent interaction between cyanidin-3-O-glucoside and sodium caseinate

•Cyanidin-3-O-glucoside (C3G) interacts with sodium caseinate nanoparticles (NaCas)•Two distinct sets of C3G binding sites on NaCas were evidenced at pH 2 and 7.•Hydrophobic effects predominate at pH 2 against electrostatic interactions at pH 7.•Increasing ionic strength affects differently the two...
